Berlina-WALL BRICK.

Application filed March 3, 1919. Serial No. 280,338.

To all whom t may concern.' i .f

, Be it known that we, ALFRED H. VILLn'r'r and HARRY S. MARTIN', citizens of the United States, respectively residiiiglat'West New York, in the county of Hudson and State of New Jersey, and at Ridgewood, county of Bergen, and State of New Jersey, have invented certain new anduseful Improvements iii4 Batlle-Wall Brick, of` which the following is a specification. l This invention relates tok balile wall brick and particularly to brick suitable for use in cross walls found in certain types of locomotive fire boxes, and for use in marine and stationary furnaces. l

Itis one of the primary objects of our invention to provide an improved brick constructed in such manner that the same` style and size of brick may be used` both fory the cross wall proper and for capping the same,

thereby reducing the number of brick pat--` terns required and simplifying the application of the brick. Y l

"We accomplish the foregoing by means of a `construction `which we have illustrated in preferred form inthe accompanying drawings, whereiny Figure 1 ing the application of our improved brick thereto; Figure 2 is a cross section through a portion of the lire box illustrating a por` tion of ythe 4refractory arch `and `our improved brick in plan View; Figure 3. is aT perspective view illustrating` `our improved brick when rusedfas a cap brick; andfFigure fl is an end elevation of a brick showing the having a shallow fire boX,-for the reason that, while our invention is suitable yfor use.

i in other connections, it is particularly usefull in connection with fire boxes of such shallow type. The fire box A is constructed in the usual manner and is provided with a plurality of circulating tubes connect-` ing the 'front' and rear Water legs. Itwill becobser is a! longitudinal section through a portion of a locomotive lfire. box illustrated that the circulating tubes at the, forward end Vapproach very closely .to `the level ofthe grates diagrammatically indicated bythe dotted line 7. f

The cross wall in the instance shown, comprises a lower; or body portion composed of a course of brick supported on the cross bearer or carrier 8 extending-.transversely of the lirey boX adjacent the front water legs, and an upper portion composed of a course of cap brick.` lIt will' be seen from inspection of Figurefl thatthe lower course consists ofour improved bricks laid on oneside, and the capor upper course, of the bricks set on edge.` The bricks of the lower course are locked in position engaging the-tubes, and the cap bricks which support the arch C composed of aplurality ofy suitable bricks of any preferred` type, are .also locked in position as will further appear.

The improved'form of brickwill `be described with'xrefe'rence tothe `positionit occupies-when being used asa` capwbrick, attention being directed particularly to FiguresBand/l. c l i i,

From inspection ofi these figures, it will be seen that the sides 9 and 1,0 of the brickr are flat, as is thebottom of the brick, indicated atllp Theitop of the brick `on one side or facethereof, is chamfered beyond the median plane of the `brick asindicated at 12, andonthe ,other side it is provided with 'a curved or rounded surface `13, which merges into the-face, or side 9 ofthe brick.` It willbe seen, therefore, .that the top fof the brick is somewhat of an'inverted 1V-` shape in form. The ends 14 and 15 of the brick each have a portion thereof cutaway to provide a socket-like rec-esswl radapted toiit the circulation tubes 6; The end portions i 17.` and 18 of the` top portion of the brick are Iinclined as indicated in Figures 3 and 4`,for the purpose of permitting such top portion to be inserted between tubes.

',Referring now-again to Figure 1, it will be seentliat the lower course of thewcrossk wall is vcomprised of our improvedbrick laid on the cross bearer or carrie'n 8-with the sidel 10y faced downward.'k In'this `position the brickswill engage `the circulation-tube 6 in 4 brick in position.

such manner that forward movement of the course of bricks is prevented. By this means, in conjunction with the. lip 19 of the cross bearer, it will be seen that the lower course of bricks is substantially locked in place, asl against longitudinal displacement. The cap bricks rest on the bricks of the lower course with their socket portions yluengagingl thevcirculation tubes @,sucli engagement preventing the cap bricks from shifting forwardly. The weight ofthe arch C prevents the cap brick from shifting rearwardly, the arrangement locking the cap Vertical jostling of the lower course of brick is prevented by virtue of 'the'fa'c't that'the cap brick sockets eiigage the circula-tion tubes and thereby 'prevent-upward movement of'the capbricks, which in turn prevent any upward displacement ofthelower 'course'of bricks. The lower course of the arch bricks engage the rounded surfaces 13 of the cap bricks, an arrangement which permits the bricks to accommodate themselves to differences in the inclination of-the tubes.

- It willbe seen from the foregoing that we have provided a simple form of brick which may be utilized both for the courses of the cross wall and to cap the cross wall, the constructionfbeing such that all of the bricks are securely locked in position. It willbe obvious'that-the bricks are simple in application and thatvthe number of patterns, and therefore the cost, is reduced.v
